The integrators, input/output tables and multipliers were located along the side of the machine and were connected via a series of cross shafts and metal gears.
Dr. Vannevar Bush and the Differential Analyzer (1931)
|
The Differential Analyzer was an analog device that was
reported to be the most accurate calculating device of its time. The Differential Analyzer
was based on metal rods and gears. There were eighteen shafts that ran lengthwise through
the machine. The integrators, input/output tables and multipliers were located along the side of the machine and were connected via a series of cross shafts and metal gears. |
